Board feet, or “bf,” is a measurement used in the construction industry to determine the quantity of material needed. One board foot is equal to a square foot of insulation that is one inch thick. So, for example, if you have an insulation area that measures 500 square feet and you want to apply open-cell foam to a thickness of 2 inches, you would need 1,000 board feet of insulation.

Keep in mind that the actual cost you will pay can vary based on other cost factors mentioned earlier, such as accessibility, labor rates, and regional pricing differences. Additionally, if you require additional services like air sealing or removal of existing insulation, these services may incur additional costs.

It’s also worth considering the long-term cost savings that open-cell spray foam insulation can offer. Due to its higher R-value per inch, open-cell foam provides good thermal insulation and can contribute to lower energy bills. It also offers excellent soundproofing capabilities, enhancing the comfort of your living or working space.

Now that we have a sense of the average cost of open-cell spray foam insulation, let’s explore the cost of closed-cell spray foam insulation.

When considering the cost of spray foam insulation, it’s important to factor in the size of the area to be insulated, the type of spray foam used, and the labor costs for installation. It’s also a good idea to get quotes from multiple contractors to ensure you’re getting a fair price.

Average Cost of Closed-Cell Spray Foam Insulation

Closed-cell spray foam insulation typically has a higher cost compared to open-cell foam, but it also offers superior insulation performance and other advantages. The average cost of closed-cell spray foam insulation ranges from $1.00 to $1.50 per board foot.

As mentioned earlier, the cost can vary depending on factors such as the size of the area to be insulated, location, and insulation thickness. The density and insulating properties of closed-cell foam contribute to its higher price point compared to open-cell foam.

When considering the cost of closed-cell spray foam insulation, it’s important to factor in its long-term benefits. Closed-cell foam offers a higher R-value per inch, indicating its superior insulation capabilities. It provides better thermal resistance, making it an excellent choice for colder climates or areas with extreme temperature fluctuations.

In addition to its insulation performance, closed-cell foam is also more effective at air sealing. Its rigid structure and ability to fill gaps and cracks prevent air leakage, reducing energy waste and enhancing the overall energy efficiency of the building.

It’s important to note that while closed-cell spray foam insulation has a higher upfront cost, it can lead to significant energy savings in the long run. The improved insulation and air sealing properties of closed-cell foam can result in lower heating and cooling costs, making it a worthwhile investment.
